Using this installation, you can check devices of various modifications, for example AP Omega, AP 2000, and others.

Step #1

Checking the serviceability of the mask make a visual check that the mask is complete and that its elements are not damaged.

For this:

disconnect the mask from the lung demand valve;

turn the chin cup outward;

inspect the glass of the mask and its body, the body of the mask holder, the inhalation valve, the exhalation valve and the intercom;

make sure there is no damage to the panoramic glass, ruptures of the intercom membrane, or punctures of the mask body and liner.

Checking the serviceability of devices in general, they are carried out by external inspection, while:

  • connect the lung demand valve to the mask, having first checked that the sealing ring is not damaged;
  • check the reliability of fastening of the suspension system of the device, cylinder (cylinders), pressure gauge and make sure that there is no mechanical damage to components and parts.

Step #2

Check the operation of the lung demand valve, the amount of exhalation valve actuation and the amount of excess pressure in the submask space of the mask.

turn off the lung demand valve (3); open the cylinder valve (8);

move the lever (4) to the “ – »

operate the pump (5) smoothly. The moment when a click is heard and the pressure begins to increase is considered the moment the lung demand valve is turned on;

move the shift lever (4) to position " + " Slowly create excess pressure in the system and observe the readings of the pressure and vacuum gauge (9). The moment when the pressure stops increasing is considered the moment the exhalation valve (10) opens. The pulmonary valve and the exhalation valve are considered to be in good condition if the excess pressure in the submask space is 200...400 Pa, there is no air leakage through the exhalation valve, the magnitude of its operation should be greater than the submask pressure, but not exceed 600 Pa.

Checking the breathing apparatus AP on KU-9V

Step#3

Record the readings of high and reduced pressure. Check the tightness of the high and reduced pressure systems of the device.

Connect the installation hose (11) through the adapter (12) to the device being tested. Open the valve (8) of the apparatus cylinder, filled with air to operating pressure.

Take readings high pressure in the cylinder from the external pressure gauge of the device and the reduced pressure from the pressure gauge (13) of the control device should be 0.45–0.9 MPa.

Close the cylinder valve. Start the stopwatch (7).

The device is considered sealed if, within 1 minute, the drop in air pressure in the high and reduced pressure system of the device does not exceed 2.0 MPa.

Step #4

Check the serviceability of the additional air supply device and the pressure at which the alarm device is activated.

Press the button to turn on the additional supply (bypass). The additional air supply device is considered to be in working order if the characteristic sound of the air flow being released is heard - before the sound signal turns on. The alarm device is considered to be in working order if the sound signal is activated when the air pressure in the cylinder drops to 5.5–0.5 MPa.

Step #5

Checking the air pressure in the cylinder(s):

the valve of the cylinder opens and the reading is recorded on the pressure gauge, while the minimum air pressure in the RPE cylinders when going on duty (when the RPE is included in the calculation), operating pressure air in the cylinder 25.3 MPa) or 260 kgf/cm2 - for DASV.

Entry in the Inspection Log No. 1

In order for work in RPE to be safe and the combat mission to be successfully completed, each member of the unit must know and comply with certain safety requirements when operating, checking and connecting systems.

Maintenance and inspection procedures for RPE 1 and 2, as well as other work, are carried out in accordance with standards and deadlines, as well as special documentation.

The results of the implementation of the relevant work are documented in special magazines registration.

Basic concepts about the use of RPE

RPE is a device that is designed to protect the senses (breathing and vision) of a person in special conditions.

Insulating protective equipment not only protects the respiratory system from exposure to harmful substances, but also supply the defender with air suitable for breathing (for example, a device with compressed air, oxygen insulating gas mask, etc.).

Each product has individual time protective action.

Basic requirements for firefighters PPE

  • Long duration of protection (at least 60 minutes).
  • Wide range of operating temperatures (from -40 to 60 °C), and for northern regions from -50 to 60 °C.
  • An oxygen insulating gas mask must protect human organs for at least 6 hours.
  • The given gas mask must operate in the temperature range from -40 to 60 °C.

Breathing apparatuses are divided depending on the devices of general and special purpose. The procedure for checking 1 RPE is individual for each type protective agent.

Putting on, taking off and storing RPE

Putting on and taking off protective equipment is carried out only after a command is given by a senior member of the squad. When working with a gas mask you need:

  1. Remove the helmet and hold it in a comfortable position.
  2. Start the lung demand valve (to do this, take a few breaths from the protective equipment system).
  3. Release the air from under the mask.
  4. Put on

When working with breathing apparatus you should:

  1. Remove the helmet and place it between your knees.
  2. Put on protective mask.
  3. Put on a bag with a rescue device.
  4. Put on your helmet.

Important! It is prohibited to turn on the devices without following the procedure for checking 1 RPE. The preparatory and executive commands of the senior officer are: “GZDS link, gas masks (devices) TURN ON.”

Types and purpose of checks

The main checks of protective equipment include:

1. Working. This type maintenance is carried out to check the serviceability individual parts the device and its correct functioning. It is carried out directly by the owner of the PPE under the guidance of a senior officer. The check is carried out before each inclusion in the RPE. When carrying out such a check it is necessary:

  • conduct a visual inspection of the front part to ensure there is no damage to the elements;
  • test the air duct system for tightness, serviceability of the pulmonary apparatus and the pressure value at which the alarm device is triggered;
  • Lastly, the air pressure in the cylinder is checked using measuring instruments.

2. The procedure for checking 1 RPE includes:

  • testing the serviceability of the front part;
  • inspect the device for any malfunctions;
  • pressure measurement in the under-mask space;
  • checking the tightness of pressure lines and air duct systems;
  • gearbox inspection.

3. Check No. 2 - view Maintenance which is carried out during the operation of RPE, and also at least once a month if RPE was not used during this time.

4. Check No. 3 - a type of maintenance carried out on time, in full and at a given frequency, but at least once a year. All RPE in operation and in reserve, as well as those requiring complete disinfection of all components and parts, are subject to inspection.

The tightness of the pressure lines is examined in accordance with the test procedure 1 RPE SCAD.

Check No. 2 is carried out after checking No. 3, disinfection, replacement of cylinders, and securing the product to the gas and smoke protector. This check should be carried out at least once a month and after each use.

The tightness of the air duct system is checked in stages:

  • first, the fitting of the rescue device is connected to the adapter;
  • then the main breathing machine is turned off;
  • then the valve of the cylinder is opened and the air duct system of the device is filled;
  • after closing the valve, the system is kept for another 1 minute;
  • if the pressure does not exceed 1 MPa, the system is operational.

Important! If malfunctions are detected, any protective equipment is removed from and sent to the GZDS base for repair. A replacement device is provided as a replacement.

Rules for storing RPE at posts and vehicles

After checking 1 RPE, the procedure for which is established by law, the protective equipment is placed in special storage areas. Serviceable and faulty devices must be stored in special cabinets or cells in correct position. Each place is equipped with a sign indicating the inventory number and information about the owner.

Each device that is stored at the GDZS post must be clean and suitable for use.

When checking, you should pay attention to the expiration dates of individual parts of the device (for example, regenerative cartridges, oxygen cylinders).

When transporting RPE to a check or repair point, special boxes with cells are used.

DASV operational check

Immediately before each inclusion in the breathing apparatus, the gas and smoke protector checks 1 RPE.

The procedure for carrying out DASV consists of going through the following stages:

  1. Carrying out an external inspection of the mask, reliability of the connection of the lung demand valve.
  2. Next, the air tightness of the air duct system is tested. At the same time, apply the mask tightly to the face and take a small breath. The system is considered to be working if there is a lot of resistance when inhaling.
  3. After the above operations, the serviceability of the lung demand valve, outlet valve, and pressure values ​​is checked.
  4. The final stage is the report to the flight commander.

Checking security using settings

Using installations, for example KU 9V, you can check 1 RPE AP "Omega". The procedure is divided into several points:

  1. Checking the serviceability of the mask and devices by inspection.
  2. Testing the operation of the lung demand valve, the magnitude of the exhalation valve response, and the excess pressure in the space under the mask. To do this, turn off the machine, open the valve, and lightly move the lever to the off position. working position. Then operate the pump smoothly until the pressure increases. After this, move the lever to the working position and observe the readings of the pressure and vacuum gauge. When the pressure stops increasing, the exhalation valve will open. Normal indicators are: excess pressure in the space under the mask from 200 to 400 Pa, valve response value 600 Pa.
  3. At the end of testing, pressure readings are recorded and the tightness of the device systems is checked. To do this, connect the installation hose and open the cylinder valve. Next, you should take readings from the high pressure gauge in the cylinder (the norm is 0.45-0.9 MPa).
  4. To test the additional air supply device and the moment of operation of the alarm device, the additional supply is turned on. It is considered operational if there is a characteristic sound of air bleeding and a special sound signal.
  5. To check the air pressure, open the cylinder valve and record the pressure gauge readings. The normal operating pressure is considered to be 25.3 MPa (for DASV - 260 kgf/cm 2).

Operating parameters of RPE "Profi"

This breathing apparatus has the following performance characteristics:

  • the protective action time under normal conditions is 60 minutes, in emergency conditions - up to 40 minutes;
  • weight of the equipped apparatus - 16 kg, with a rescue device - 17 kg;
  • working pressure in the cylinder - 10 atm;
  • breathing resistance at the outlet - 350 MPa;
  • operating time when the alarm device is activated is at least 10 minutes;
  • average service life is 10 years.

The procedure for checking 1 RPE "Profi-M" is similar to the above.

Regulatory documentation for testing RPE

Each department of the State Health and Safety Inspectorate is required to inspect 1 RPE. The procedure, Order No. 3 of January 9, 2013, which was developed and signed by the Ministry of Civil Defense, is carried out by all services in the country.

Service personnel are obliged to know and follow these rules and orders, and carefully monitor the condition of personal protective equipment.

The provisions of the orders apply to the personnel of the centers for civil defense, emergency situations and disaster relief, specially authorized bodies (Ministry of Emergency Situations and their units).

Responsibility for the condition of instruments, apparatus and training of personnel lies with the senior rank in the unit.

As Mr. Artamonov says, good day.
A lot has been written about the complete inventory, but if you don’t have time to read, then please do so.
1. Agree in advance on the issue of time for inventory with the sales department, supply, and if the answer is storage, then with the depositors (if this is not done, then they will not allow you to calmly carry out the inventory).
2. Issue an order (general director) to conduct an inventory:
-commission
-what is being checked
-when to start and when to finish.
3.Prepare inventory sheets
-nomenclature
- quantity according to accounting data
- quantity in stock (condition, defective)
-surplus
-shortage
It is advisable to compile inventory sheets by groups of goods, how they are stored and how they will be counted.
4. At the time of the inventory, the warehouse accountant and storekeepers give receipts stating that all invoices have been posted, all goods have been received, if the collected goods have not been shipped, the order is disbanded and the invoices are cancelled.
5. The warehouse should be given at least 2-3 hours to prepare the goods for inventory: check that the goods are in their places, there are no more than one opened boxes (pallets, packs) of the same item, all receipts are placed in storage locations.
6. During the inventory, the acceptance and shipment of goods stops (if there is an urgent need, it is possible to unload the goods and put them aside, and capitalization is carried out after the inventory).
Don't forget to close the base so that no work is done in it.
7. Removal of balances is carried out on commission (i.e., in the presence of at least 3 people), the person financially responsible shows where the goods are stored but has no right to count.
For example, I count the goods and enter the data into the inventory sheet of the warehouse accountant, while the storekeepers also count, but for themselves (if the numbers differ, the storekeeper has the right to demand that the goods be counted), if all the members of the commission agree with the recalculation data, then the figure entered into the inventory list.
After filling out each sheet of the statement, it is signed by all members of the commission, and subsequently certified with a seal.
If corrections are made in the statement, they must also be certified with signatures and a seal.
8. After the withdrawal of balances is completed, all signed statements are submitted to the accounting department (for me, to the head of the document processing department).
After this, the head of the document processing department and the warehouse database administrator, who is also the warehouse accountant, enter this data into 1C.
After this, they form write-off and capitalization acts, identifying possible misgrading.
For each shortage or surplus, the financially responsible person (storekeeper) writes an explanation indicating specific reasons why this happened.
Possible reasons misgradings are identified jointly by 3 people, the warehouse manager, the head of the clearance department and the warehouse database administrator (they do not report to each other, so the likelihood of collusion is quite low). Moreover, a control check of inventory results is possible (selective, of course).
Managers of the supply department may be present at the inventory, who, together with storekeepers, resolve issues regarding commercial acts (receipts) and have the right to transfer goods from condition to scrap.
9. If there are norms for writing off goods in a warehouse, the commission may propose to the director to write off part of the missing goods according to the norms of natural loss.
10. Re-grading can be accepted for credit for goods of the same group and must be the same in quantity.
11. Acts of write-off, capitalization and regrading are displayed with prices, if the difference is positive, then the goods are simply credited, if negative, then the difference is attributed to the financial account responsible person.
12. Based on the results of the inventory, the database is adjusted.

If the warehouse uses barcoding and has reading devices, then the procedure changes somewhat, but purely technically.
Something like that, good luck.

Working check RPE is carried out:

  • Before using RPE in an unsuitable for breathing environment, an operational check is carried out in accordance with the requirements of the RPE manufacturer's operating manual.
  • When replacing a RPE cylinder at the site of fire extinguishing in an environment unsuitable for breathing (classes, training), a working check of the RPE is carried out.
  • A working check of the RPE is carried out by a gas and smoke protection specialist at the command of the GDZS flight commander (training leader): “Link, check your breathing apparatus”. The operating test time should not exceed 1 minute.

At the end of the working check, the gas and smoke protector reports to the GDZS flight commander (leader of the lesson) about readiness for switching on and the value of the working pressure in the cylinder (cylinders): “Gas and smoke protector Petrov is ready to turn on, pressure is 280 atmospheres”.

Permission to include a gas and smoke protection device in the RPE is given by the GDZS flight commander (training leader) after reporting to him about positive results operational check, serviceability and completeness: “Link, put on the breathing apparatus”.

Inclusion in RPE is carried out directly at the entrance to an environment unsuitable for breathing. The GDZS unit returns from an unsuitable for breathing environment only in full force. Switching off from RPE is carried out at fresh air at the command of the flight commander: "Link, from breathing apparatus turn off".

Procedure for carrying out a working inspection

Need to check:

  1. The serviceability of the mask and the correct connection of the lung demand valve to it.
  2. Vacuum tightness of the apparatus.
  3. Operation of the lung demand valve and mask exhalation valve.
  4. Triggering of the alarm device.
  5. Air pressure in the cylinder(s).

The serviceability of the mask and the correct connection of the lung demand valve to it are checked visually. Check the absence of damage to the mask elements and the reliability of the connection between the lung demand valve and the mask, and for type 2 additionally:

  • by rotating the lung demand valve 2 (Figures 6 and 7), make sure that the latch 2.1 is closed;
  • make sure that the bypass handwheel 2.4 is in the off position or turn it off by turning it 90° clockwise.

Checking the tightness of the apparatus for vacuum is carried out with the cylinder valve(s) closed. To check, you need to press the mask tightly to your face and try to take a shallow breath.

ATTENTION!!! ATTEMPTING TO TAKE A SHARP DEEP BREATH CAN LEAD TO LUNG BAROTRAUMA!

If, when inhaling, a large resistance is created that does not allow further inhalation and does not decrease within 2-3 s, the device is considered sealed.

For this:

  • turn off the lung demand valve mechanism, for which press button 2.2 all the way (Figures 5, 6 and 7), fix it for 1 - 2 s, then smoothly release it;
  • open the valve of the cylinder (one of the cylinders);
  • put on a mask and make adjustments;
  • after the first deep breath, make sure that the lung demand valve has turned on and excess pressure has arisen in the cavity of the mask, for which they take several breaths and exhalations;
  • then, holding their breath, they put their finger under the seal of the mask and make sure that there is a constant flow of air from under the mask;
  • remove your finger from under the seal and, holding your breath for about 5-10 seconds, listen to make sure there is no air leakage.

If a leak is detected, adjust the position of the mask by tightening the straps, avoiding overtightening, and recheck the absence of leaks. After this, close the valve, turn off the lung demand valve and remove the mask.

Checking the operation of the alarm device is carried out in the following sequence:

  • open and close the valve of the cylinder (one of the cylinders);
  • by carefully pressing the bypass button and holding it in this position (type 1) or smoothly turning the bypass handwheel (type 2), bleed air from the internal cavities of the device, while simultaneously observing the readings of the device’s pressure gauge;
  • at the moment the sound signal occurs, note the pressure gauge reading and make sure that it meets the requirements of the operating manual for the breathing apparatus.

The air pressure in the cylinder(s) is checked with the valve(s) open using a pressure gauge. When checking, record the pressure gauge reading, which must be at least 25.3 MPa (260 kgf/cm2).
